Questions & Answers for Costa Del Mar Costa® Harpoon 400 Polarized Sunglasses


I could not find any sizing information. According to costa they make these glasses in M and L/XL. What size are these?

Unless you have a thin face, you are most likely a L/XL. The M is most likely made for women and children.

They only make them in one size. The two sizes you see displayed on the Costa website is the size of the lens and the size of the frame. The harpoon has a medium large frame and a large lens. When you see the words medium large as a size, it's not two sizes, it's one, the same way that a medium light or medium heavy fishing rod is rated. It's a little larger than medium, but not quite a large, so the size is ML.The sizes of the frames and lenses are constant, they don't change. If you want a different size, you have to choose a different frame. There are others that are similiar. A good example is the brine model, it's a ML lens with a ML frame, but the fathoms are the same frame basically (just a little rounder), but smaller, they are a M frame with L lens.

That's a little weird that they say they can make them in different sizes. As a sunglass associate, I would say compared to the different styles of Costa's, those are a large.

However, there are different styles that are comparable to the harpoon that I would consider to be a medium and an extra large.

The Triple Tail is the closest medium version of the Harpoon. It is almost exactly like the Harpoon, only smaller.

The Hammerhead is the closest extra large in my opinion.

However, there are 12 new styles of Costa Del Mar sunglasses that I have yet to see, so I'm not sure if one of those are more comparable for the XL.
